When to dive in Cozumel

There is no bad time for diving in Cozumel. Water temperatures remain constant year-round 78-82ºF (25-28ºC) and cool only slightly during the winter months of September-December. You can dive approximately 300 days of the year - a glorious long season for divers.

Diving in Cozumel is famous for easy drifts but currents can be strong during the seasonal transition - best suited to advanced divers. Divers choosing to plunge below the surface at this time are rewarded with more sharks and eagle rays.

November-March in particular are the best months for bull shark sightings. May-September brings warm waters, uncrowded dive sites and generally calm conditions. This is the best time to dive in Cozumel if you like it warm, but diving in the Caribbean Sea is pleasant at any time of year.
